Okay, okay, it might have been weeks since we finished Netflix's addictive Making A Murderer series, but we're finding it very hard to drop it. Especially when new pieces of information like THIS keep surfacing.

Steven Avery, who ***SPOILER ALERT*** is currently serving life imprisonment for the murder of Theresa Halbach, a crime he insists he didn't commit, has got himself a new lawyer. Kathleen Zellner, on the back of the widespread popularity of the documentary series, has been very vocal about her support for Steven Avery's innocence, and is helping him to communicate that to the outside world as much as possible.

But a recent tweet from Zellner, showing a photograph of a letter written by Avery himself, seems to indicate that he knows exactly who DID kill Theresa Halbach.

The letter reads: "To my supporters: I want everyone to know that no one in my family including me was involved in the murder of Teresa Halbach. It is obvious who killed Teresa but the Manitowoc Cops chose not to investigate him so they could frame me. Just like the first time."

Obviously, if Steven was so adamant about knowing who he believes is to blame, it does beg the question why he's never piped up about it before. Having said that, though, I can seem to remember from one of the episodes that it's not legally sound in a defence case to bring in random accusations towards people outside the case. So perhaps that's why Steven has only been able to discuss this now.

But if it does nothing else, it rubbishes the theory going round that Steven's brother-in-law, Scott Tadych, and his step-son Bobby Dassey - both of whom testified against Steven in his trial - might have been to blame. But then that was just one of many theories, anyway. So WHO BLOODY KNOWS.
